FBG filter

AOS broadband FBG filter 1550nm

By utilizing the "chirp" (linear variation of the period within the FBG structure) fiber Bragg grating technology, we can provide a very wide bandwidth and high suppression for FBGs. We can provide a wide range of center wavelengths, bandwidths, and reflectivity.

AOS 100GHz DWDM FBG Filter

Fiber Bragg Grating is a widely used component in optical communication. FBG serves as a narrowband fiber filter. Bragg gratings are printed into optical fibers through holographic technology. They can be produced using standard single-mode fibers or special fibers, namely radiation mode suppression fibers used to reduce cladding mode losses.

Electric tunable fiber Bragg grating filter

Xiaoxiao Photon's tunable fiber Bragg grating filter (OETFG-200) can provide a stable adjustable range, simple structure, high resolution, and long lifespan. This adjustable filter adopts Fiber Bragg Grating (FBG) technology, which can be used for both transmission mode and reflection mode, or only for reflection mode (as required). As an option, a fiber optic circulator can be integrated to provide a bandpass signal for the output port. The cyclist can be used in the range of 1060nm, 1310nm, and 1550nm. The band stop option without the need for a loop protector is also available. In the bandstop version, the communication signal is reflected to the input end.

Thermally tunable fiber Bragg grating filter

The temperature tunable fiber Bragg grating filter (OETFG-300) of Xiaoxiao Photon utilizes a thermoelectric cooler (TEC) to fine tune the center wavelength of FBG in the range of 1 nm. The specifications of fiber Bragg grating (FBG) filters can be fully customized and defined by customers (with some limitations in application). When in reflective mode, the customer needs to use an external optical ring resonator. The circulators can be obtained from Xiaoxiao Photon in the range of 1060nm, 1310nm, and 1550nm, and can be provided upon request.
